15 Claims, No Drawings 1 TRIAZOLYLTHIOPHOSPHORIC ACID ESTERS The present invention relates to new triazolylthiophosphonic acid esters, to processes for their production, and to the use thereof for pest control.

The new triazolylthiophosphonic acid esters correspond to the formula:

R N ---N wherein R, represents a lower alkyl radical, a cycloalkyl radical, or a phenyl radical optionally substituted by chlorine and/or bromine, of the symbols R and R any one represents hydrogen, a lower alkyl radical, a cycloalkyl radical, a phenyl radical optionally substituted by chlorine, and the other the radical wherein R, represents a lower alkyl radical or the phenyl radical, and R a lower alkyl radical.

By a lower alkyl radical is meant in each case a straight-chain or branched radical having 1 to 5 carbon atoms, e.g. methyl, ethyl, n-propyl, isopropyl, n-butyl and n-pentyl, as well as isomers thereof. Preferred as cycloalkyl radicals are the cyclopentyl and cyclohexyl radical.

Preferred compounds because of their effect are compounds of formula I wherein R, represents C C alkyl, a (X),. C,,H,-,,, radical wherein X is chlorine or bromine and n is a number from 0 to 2, such as phenyl, 3-chlorophenyl, 4-chlorophenyl, 4-bromophenyl or 2,5-dichlorophenyl; R represents hydrogen, phenyl, C,-C,-alkyl or R represents phenyl or in which ud'rili symbols X and Y represents hydrogen, a lower alkyl radical, a cycloalkyl radical, or a phenyl radical optionally R Hal P 4 (III) wherein Hal represents chlorine or bromine, and R, and R have the meanings given under formula l, in the presence of an acid-binding agent; or

b. the reaction of a metal salt of a hydroxytriazole of formula ll with a thiophosphonic acid halide of formula III.

Salts of hydroxytriazoles of formula [I which are suitable for the process according to the invention are, in particular, the alkali metal salts; there are, however, other suitable salts, e.g. salts of monovalent heavy metals.

Suitable as acid-binding agents are, e.g. the following bases: tertiary amines such as triethylamine, dimethylaniline, pyridine, pyridine bases, inorganic bases such as hydroxides and carbonates of alkali metals and alkaline-earth 'metals, preferably sodium and potassium carbonate.

The reactions can be preferably carried out in solvents or diluents inert to the reactants. The following are, for example, suitable for this prupose: aromatic hydrocarbons such as benzene, toluene, benzines, haloge nated hydrocarbons, chlorobenzene, polychlorobenzenes, bromobenzene, chlorinated alkanes having I to 3 carbon atoms, ethers such as dioxane, tetrahydrofuran; esters such as ethyl acetate; ketones such as methyl ethyl ketone, diethyl ketone, nitriles, etc.

The starting materials of formula [I are in some cases known compounds which can be produced by processes known per se. These compounds are obtained, for example, by the reaction of a correspondingly substituted semicarbazide with orthocarboxylic acid ethyl ester, e.g. orthoformic acid ethyl ester; or by the acylation firstly of a correspondingly substituted semicarbazide, and subsequent ring closure under alkaline conditions (cp. e.g. .l.B. Chem. Ber. 56, 1797).

The active substances of formula I are suitable for the control ofthe most diverse pests of the vegetable or animal kingdom.

They are effective, in particular, against all development stages such as, eg eggs, larvae and pupae of insects and members of the order acarina, such as mites and ticks.

The compounds of formula l can be used, for example, to combat the following insects or members of the order acarina:

Insects of the families:

Teltigonidae Gryllidae Gryllotalpidae Blattidae Peduviidae Phyrrhocoriae Cimicidae Delphacidae Alphididae Diaspididae Pseudococcidae Scarabaeidae Dermestidae Coccinellidae Tenebrionidae Chrysomelidae Bruchidae Tineidae Noctindae Lymatriidae Pyralidae Culicidae Tipulidae Stomoxydae Trypetidae Muscidae Calliphoridae and Pulicidae Acarida of the families:

lxodidae Argasidae Tetranychidae and Dermanyssidae.

The insecticidal or acaricidal action can be substantially broadened and adapted to suit the given circumstances by the addition of other insecticides and/or acaricides. Suitable additives are, amongst others, e.g. the following active substances:

The compounds of formula I can be used on their own or together with suitable carriers and/or additives. Suitable carriers and additives may be solid or liquid, and correspond to the substances common in formulation practice, such as, eg natural and regenerated substances, solvents, dispersing agents, wetting agents, adhesives, thickeners, binders and/or fertilisers.

For application, the compounds of formula I can be processed into the form of dusts, emulsion concentrates, granulates, dispersions, sprays, or solutions, the formulation of these preparations being effected in a manner commonly known in practice. Also to be mentioned are cattle dips and spray races, in which aqueous preparations are used.

The agents according to the invention are produced in a manner known per se by the intimate mixing and- (DlTHlA- /or grinding of active substances of formula I with the suitable carriers, optionally with the addition of dispersing agents or solvents which are inert to the active substances. The active substances can be obtained and used in the following preparation forms: solid preparations:

dusts, scattering agents, granulates, coated granulates, impregnated granulates and homogeneous granulates; liquid preparations:

a. water dispersible active substance concentrates:

wettable powders, pastes, emulsions;

b. solutions;

The solid preparations (dusts, scattering agents) are produced by the mixing of the active substances with solid carriers. Suitable carriers are, e.g. kaolin, talcum, bole, loess, chalk, limestone, ground limestone, Attaclay, dolomite, diatomaceous earth, precipitated silicic acid, alkaline-earth silicates, sodium and potassium aluminium silicates (feldspar and mica), calcium and magnesium sulphates, magnesium oxide, ground synthetic materials, fertilisers such as ammonium sulphate, ammonium phosphate, ammonium nitrate, urea, ground vegetable products such as bran, bark dust, sawdust, ground nutshells, cellulose powder, residues of plant extractions, active charcoal, etc., alone or in admixture with each other.

The particle size of the carriers is for dusts advantageously up to about 0.1 mm; for scattering agents from about 0.075 mm to 0.2 mm; and for granulates 0.2 mm

or coarser.

To these mixtures may also be added additives stabilising the active substance, and/or non-ionic, anion-' active and cation-active'substances which, for example, improve the adhesiveness of the active substances on plants and on parts of plants (adhesives and agglutinants), and/or ensure better wettability (wetting agents) and dispersibility (dispersing agents).

The following substances are, for example, suitable:

olein/chalk mixture, cellulose derivatives (methyl cellulose, carboxymethyl cellulose), hydroxyethylene glycol ethers of monoalkyl and dialkyl phenols having to ethylene oxide radicals per molecule and 8 to 9 carbon atoms in the alkyl radical, ligninsulphonic acid, the alkali metal and alkaline-earth metal salts thereof, polyethylene gylcol ethers (carbowaxes), fatty alcohol polyglycol ethers having 5 to ethylene oxide radicals per molecule and 8 to l8 carbon atoms in the fatty alcohol moiety, condensation products of ethylene oxide, propylene oxide, polyvinylpyrrolidones, polyvinyl alcohols, condensation products of urea and formaldehyde, as well as latex products.

Water-dispersible concentrates of active substances, i.e. wettable powders, pastes and emulsion concentrates, are agents which can be diluted with water to obtain any desired concentration. They consist of active substance, carrier, optionally additives which stabilise the active substance, surface-active substances, and anti-foam agents and, optionally, solvents.

The wettable powders and pastes are obtained by the mixing and grinding of the active substances with dispersing agents and pulverulent carriers, in suitable devices, until homogeneity is obtained. Suitable carriers are, e.g. those previously mentioned in the case of solid preparations. It is advantageous in some cases to use mixtures of different carriers. As dispersing agents it is possible to use, e.g.: condensation products of sulphonated naphthalene and sulphonated naphthalene derivatives with formaldehyde, condensation products of napthalene or of naphthalenesulphonic acids with phenol and formaldehyde, as well as alkali. ammonium and alkaline-earth metal salts of ligninsulphonic acid, also alkylarylsulphonates, alkali metal salts and alkalineearth metal salts of dibutyl naphthalenesulphonic acid, fatty alcohol sulphates such as salts of sulphated hexadecanols, heptadecanols, octadecanols. and salts of sulphated fatty alcohol glycol ether, the sodium salt of oleyl methyl tauride. ditertiary acetylene glycols, dialkyl dilauryl ammonium chloride, and fatty acid alkalimetal and alkaline-earth metal salts.

Suitable anti-foam agents are, e.g. silicones.

The active substances are so mixed, ground. sieved and strained with the above mentioned additives that the solid constituent in the case of wettable powders has a particle size not exceeding 0.02 to 0.04 mm, and in the case of pastes not exceeding 0.03 mm. For the preparation of emulsion concentrates and pastes, dispersing agents are used such as those mentioned in the preceding paragraphs, organic solvents and water. Suitable solvents are, e.g. alcohols, benzene, xylene, toluene, dimethylsulphoxide, and mineral oil fractions boiling in the range of l20 to 350C. The solvents must be practically odourless, nonphytotoxic, and inert to the active substances.

Furthermore, the agents according to the invention can be used in the form of solutions. For this purpose, the active substance, or several active substances, of the general formula l is dissolved in suitable organic solvents, solvent mixtures, or water. As organic solvents itis possible to use aliphatic and aromatic hydrocarbons, their chlorinated derivatives, alkylnaphthalenes, mineral oils on their own or in admixture with each other.

The content of active substance in the above described agents is between 0.1 and it is to be mentioned in this connection that in the case of application of the agents from an aeroplane, or by means of some other suitable application devices, concentrations of up to 99.5% can be used, or even the pure active substance.
